YES -Troubleshooting is complete. If any other Temporary DTCs or DTCs were indicated in step 11, go 
to the INDICATED DTCS TROUBLESHOOTING. 

NO -If the screen indicates FAILED, check for poor connections or loose terminals at the FTP sensor and 
the ECM/PCM, then go to step 1. If the screen indicates NOT COMPLETED, keep idling until a result 
comes on. 

DTC P0452: FTP SENSOR CIRCUIT LOW VOLTAGE 

1. Turn the ignition switch ON (II).  

2. Clear the DTC with the HDS.  

3. Turn the ignition switch OFF.  

4. Remove the fuel fill cap.  

5. Turn the ignition switch ON (II).  

6. Check the FTP SENSOR in the DATA LIST with the HDS. 

Is about - 7.3 kPa (--2.16 in.Hg, --55 mmHg), or 0.3 V or less indicated?  

YES -Go to step 10. 

NO -Go to step 7. 

7. Install the fuel fill cap.  

8. Start the engine.  

9. Monitor the OBD STATUS for DTC P0452 in the DTCs MENU with the HDS. 

Does the screen indicate FAILED?  

YES -Go to step 10. 

NO -If the screen indicates PASSED, intermittent failure, the system is OK at this time. Check for poor 
connections or loose terminals at the FTP sensor and the ECM/PCM. If the screen indicates NOT 
COMPLETED, go to step 4 and recheck. 

10. Turn the ignition switch OFF.  

11. Disconnect the FTP sensor 3P connector.  

12. Turn the ignition switch ON (II).  

13. Check the FTP SENSOR in the DATA LIST with the HDS.

YES -Troubleshooting is complete. If any other Temporary DTCs or DTCs were indicated in step 26, go 
to the INDICATED DTCS TROUBLESHOOTING. 

NO -If the screen indicates FAILED, check for poor connections or loose terminals at the FTP sensor and 
the ECM/PCM, then go to step 1. If the screen indicates NOT COMPLETED, keep idling until a result 
comes on. 

28. Turn the ignition switch OFF.  

29. Reconnect all connectors.  

30. Update the ECM/PCM if it does not have the latest software (see UPDATING THE ECM/PCM ), or 

substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ).  

31. Start the engine, and let it idle.  

32. Check for Temporary DTCs or DTCs with the HDS. 

Is DTC P0452 indicated?  

YES -Check for poor connections or loose terminals at the FTP sensor and the ECM/PCM. If the 
ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING THE 
ECM/PCM ), then go to step 31. If the ECM/PCM was substituted, go to step 1. 

NO -Go to step 33. 

33. Monitor the OBD STATUS for DTC P0452 in the DTCs MENU with the HDS. 

Does the screen indicate PASSED?  

YES -If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, 
replace the original ECM/PCM (see ECM/PCM REPLACEMENT ). If any other Temporary DTCs or 
DTCs were indicated in step 32, go to the INDICATED DTCS TROUBLESHOOTING. 

NO -If the screen indicates FAILED, check for poor connections or loose terminals at the FTP sensor and 
the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see
